Description
Technical Field
The invention relates to the field of pesticide preparation, in particular to a novel preparation process of spherical water dispersible granules, which can be applied to different types of pesticide products.
Background
In the pesticide product, the water dispersible granule has unique advantages compared with the traditional dosage form, namely: when in use, no dust flies, thereby reducing the pollution to the environment, being safe to users and reducing the toxicity of highly toxic varieties; compared with wettable powder and suspending agent, the content of active ingredients is high, the relative density of the product is large, the volume is small, and the packaging, the storage and the transportation are convenient; the storage stability and the physical and chemical stability are better, and particularly, the preparation formulation can ensure the stability of the active ingredients compared with a suspending agent for the pesticide which is unstable in water.
In the preparation process of the water dispersible granule, granulation and drying are the most critical two processes. Currently, the existing granulation methods (the product is spherical particles) can be classified into two types: first, wet granulation, such as high tower spray method (tower height more than 30 m). The disadvantages are that: (a) the investment of basic equipment is large; (b) the energy consumption is high; (c) the variety switching is difficult (the pesticide is a large market with multiple varieties, different varieties aim at different diseases, insects and pests, the pesticide can not be used by mistake or used in a mixed way, the cross contamination among different varieties needs to be strictly controlled, and the requirement of the switching product on equipment cleaning is very high); (d) the uniformity of the product particles is difficult to control; (e) heat sensitive materials cannot be processed. Because high temperature drying has destructive influence on effective components of heat-sensitive materials, if a low temperature drying mode is adopted, the product performance is damaged because the detention time of the materials when falling in a space (according to the height of a spray drying tower) is fixed and drying cannot be carried out due to insufficient temperature. And secondly, dry granulation, including an extrusion granulation method, a fluidized bed granulation method and a disc granulation method. The extrusion granulation method (for example, "a dimethomorph water dispersible granule and a preparation process thereof" disclosed in Chinese invention patent CN101379972A, and "a pesticide water dispersible granule containing an organic silicon surfactant and a preparation method thereof" disclosed in Chinese invention patent CN 101632355A) has the following disadvantages: the finished product rate is low, the uniformity of the product is poor, the physical property of the product is poor, the production environment is poor, more importantly, the finished product is compact, has no gap and has poor water-entering disintegration effect. Fluidized bed granulation method: the disadvantages are that: high energy consumption, high production operation difficulty, low yield and high loss. The disk granulation method (for example, the Chinese utility model patent CN203778031U discloses a machine for granulating by an extrusion method of pesticide water dispersible granules) has the defects that: more dust, poor production environment, poor physical properties of products and low yield of products. The existing drying methods (except the high tower spraying method) can also be classified into a first type and a boiling drying method. The disadvantages are that: (a) the large flow rate of hot air evacuation is an important reason for its high energy consumption; (b) the particles collide with each other in a boiling state, and many particles are broken in the collision, so that secondary dust is generated, the loss of raw materials is increased, the yield cannot be improved, and the cost of dust pollution in later granulation is increased. (c) Products unsuitable for processing heat-sensitive raw materials. And secondly, drying in an oven. The disadvantages are that: the heat conduction is not uniform, resulting in unstable product quality. The product quality is finally influenced, the materials need to be turned manually, the labor intensity of operators is increased, the materials cannot be prevented from being contacted with the materials to be dried, the physical health of the operators is damaged, and the environment is polluted by flying dust.

Step S3, humidifying and granulating: the materials are placed in a granulating device, rolled, humidified and sheared simultaneously, and spherical particles with uniform particle quality are formed. If wet granulation is adopted, the air flow crushing equipment (the equipment applied in the step 2) which is the mainstream equipment commonly used in the pesticide industry is abandoned, so that the resource is greatly wasted, the popularization and the popularization of a new process are not facilitated, and the air flow crushing equipment (the air flow crushing equipment) in the existing pesticide industry can be utilized to the maximum extent, and the upgrading and updating work of the whole industry is facilitated to be smoothly promoted. In this example, the granulation was performed at room temperature, and the problem of granulation of the thermosensitive material was successfully solved. The method is carried out under the normal pressure, namely, the inside of the granulating device is in a non-extrusion state, so that the problems of poor physical properties of products in an extrusion granulating method and the like are solved.

By adopting the static method, the mutual collision of the particles before drying can be effectively avoided, the particle damage and the generation of secondary dust are avoided, the material loss is reduced, and the primary yield of the product is effectively improved. And an automatic overturning mode is adopted, so that the problem that the material is heated unevenly can be solved.

Wherein, the conveying direction is opposite between the upper and lower adjacent conveyer belts and the lower conveyer belt staggers a distance for the upper conveyer belt along the conveying direction. The process of use is as follows, the granulated material is sent to the uppermost layer of the conveyer belt by a feeder. The material of upper conveyer belt is carried to the end along direction of delivery, receives the effect of material self gravity, and the material falls down to the conveyer belt of lower floor with the mode of upset by oneself, carries along direction of delivery again. The process is repeated until the lowest layer of the conveyer belt falls into the blanking hopper 24.
The conveying speed of each layer of the conveyor belt can be set independently. Under the condition of the conveyer belt with the same unit length, the conveying speed is changed, the detention time of the materials on the conveyer belt can be adjusted, and the heating time of the materials on the conveyer belt is further controlled.
